5ea Inner 13mm 0.5inch Clip EMI Filter ferrite Bead ferrite Cable ferrite Clamps ferrite snap ferrite Clip Noise Cancel ferrite Ring (Grey)

My business relies heavily on these products, so I'm purchasing them in bulk to resolve noise issues everywhere. When I turned on my home stereo, the home stereo system made a loud buzzing noise while I was talking on the ham radio. It is recommended that you use 6MHz or 7MHz. One MHz. I wrapped about five turns around these cores for each audio cable, and the problem is solved. It has no longer affected my stereo when I key up the radio. It's back to pure audio bliss. Using these to reduce inverter pickup with SDR radios and wrapping on power cables has also been effective for me. I've used these as chokes and they're great. inner diameter (ID) of this cable is 13mm, and that is large enough to accommodate multiple turns of thinner wire (for example, RCA stereo cables). It's choking effect increases with the number of turns.

Once you close the clips, they snap into position and the effect is very good. If needed, the line can be opened if necessary, but it is an inline line. The design is very nice. As you can see, the peak choking effect continues to higher frequencies, indicating that these could be very effective at even higher frequencies. I have a VNA, hence tested these, and the resistance is shown in the following table, for 5 turns of wire. As far as I know, 24MHz was as high as I needed for my use, so I don't know where the peak frequency is. I've rephrased the last phrase to 1MHz,.

The 60 cycle buzz that was caused by LED shop lights was heard on my FM radio station. In this way I can work in the dark and still have light or not listen at all. It's a good product whichever way you look at it.

I have no problems with my coaxial cable.
